Definitions
- the present invention relates to the overall technical field of agricultural machinery. It relates more specifically to a mower comprising:
- a mechanism for grouping windrows comprising a longitudinal conveying device and a transverse conveying device.
- Such a mower is known in the state of the art. Indeed, VICON's “KMT/KMR 2400-3000-3200” brochure describes a trailed conditioning mower equipped with a belt-type grouper.
- this mower comprises a cutting mechanism connected to a frame resting on the ground by means of two wheels.
- the belt-type grouper arranged behind the cutting mechanism, is also supported by the frame.
- the cutting mechanism is intended to cut a standing product, for example grass.
- the grouper advantageously allows the product cut in at least two consecutive passes of the mower to be grouped together into a single windrow. What happens is that, during a first pass, the grouper of this known machine is pivoted upward into an inactive position.
- the product cut by the cutting mechanism is therefore deposited on the ground in the continuation of the mower.
- the grouper is lowered into an active position.
- the product cut by the cutting mechanism is transported, by means of the belt-type grouper, to be deposited to the side of the mower and onto the windrow from the first pass.
- the grouper is made up of a first belt running along a longitudinal axis of the mower and of a second belt arranged transversely to the mower.
- the first belt is intended to convey the forage from the cutting mechanism to deposit it onto the second belt.
- the latter in turn transports the forage to deposit it on the ground to the side of the mower.
- the first belt is produced by means of an endless belt wrapped around two cylinders.
- One of the cylinders, the axis of which is substantially horizontal, is arranged behind the cutting mechanism.
- the second cylinder identical to the first cylinder, is, for its part, arranged above the second belt.
- This known embodiment of a longitudinal conveying device does, however, have a drawback. Specifically, in order to convey all of the cut product, the first belt is practically as wide as the cutting mechanism. In the case of mowers with wide cutting widths, it is then commonplace for the width of the first belt to exceed the distance between the two cylinders of which it is made. Such a configuration makes the endless belt difficult to guide over the cylinders. During work, this belt has a tendency to slip along the axis of said cylinders and therefore to rub against the structure of the grouper. This rubbing reduces the performance of the grouper and may even lead to tearing of the endless belt.
- the purpose of the present invention is to overcome this drawback of the state of the art.
- the mower according to the present invention is one wherein said longitudinal conveying device comprises at least one roller, the longitudinal axis of which is substantially perpendicular to a direction of forward travel of said mower, driven in rotation about said longitudinal axis so that its periphery transports the product, cut by the cutting mechanism, toward the rear of said mower.
- said mower does not have the drawback, described hereinabove, associated with the use of a very wide belt.
- FIG. 1 depicts, in side view, a mower according to the present invention
- FIG. 2 depicts, viewed on arrow II defined in FIG. 1, the mower of FIG. 1,
- FIG. 3 depicts, viewed in perspective on arrow III defined in FIG. 2, and on a different scale, an exemplary embodiment of the windrow grouping mechanism
- FIG. 4 depicts, viewed in perspective on arrow IV defined in FIG. 2, and on a different scale, the windrow grouping mechanism of FIG. 3 in the inactive position.
- FIGS. 1 and 2 The mower 1 depicted in FIGS. 1 and 2 is trailed in a direction and sense of forward travel indicated by the arrow 2 .

- said mower 1 comprises a frame 3 running along the ground by means of two wheels 4 .
- Said frame 3 supports, on one hand, a cutting mechanism 5 and, on another hand, a windrow grouping mechanism 6 .
- said frame 3 is connected to the rear of a tractor vehicle 7 by means of a drawbar 8 .
- Said drawbar 8 is connected to said frame 3 by means of an articulation 9 the axis 9 a of which is directed upward.
- Said articulation 9 advantageously allows said mower 1 to occupy, with respect to said tractor vehicle 7 , a transport position and at least one work position.
- said articulation 9 is situated at least substantially in a vertical mid-plane of said mower 1 .
- said mower 1 can be arranged in the continuation of said tractor vehicle 7 , as depicted in FIG. 2, to make it easier to transport by road.
- said drawbar 8 By pivoting said drawbar 8 with respect to said frame 3 about said articulation 9 , said mower 1 can also be moved to the right or to the left of said tractor vehicle 7 .
- These two positions, used during work advantageously allow said mower 1 to work back and forth.
- the pivoting of said drawbar 8 and therefore the placement in the work position or the placement in the transport position, is brought about by means of a ram 10 connected, on one hand, to said frame 3 and, on another hand, to said drawbar 8 .
- FIG. 1 said frame 3 has been partially depicted in section so as to make said windrow grouping mechanism 6 visible.
- FIGS. 1 and 2 it will also be noted that not all of the length of said drawbar 8 has been depicted.
- said cutting mechanism 5 is connected to said frame 3 by means of a suspension device.
- said cutting mechanism 5 rests at least partially on the ground 12 .
- Said suspension device advantageously allows at least some of the weight of said cutting mechanism 5 to be transferred to said frame 3 .
- said suspension device allows said cutting mechanism 5 to follow the unevenness of said ground 12 independently of said frame 3 .
- Such a suspension device is known to those skilled in the art and will therefore not be described further and, for reasons of clarity, has not been depicted in the figures.
- Said cutting mechanism 5 comprises cutting members 11 intended to cut a standing product, these members being arranged in a line at least substantially perpendicular to said direction of forward travel 2 .
- Each cutting member 11 depicted symbolically in FIG. 2, is driven in rotation about an upwardly-directed respective axis 11 a.

- the cutting members 11 and the treatment device 13 of said cutting mechanism 5 are driven in rotation, off a power take-off of said tractor vehicle 7 , by means of transmission members 15 .
- Said transmission members 15 are known to those skilled in the art and will therefore not be described further.
- said windrow grouping mechanism 6 is intended to group together, into a single windrow, the product cut during at least two consecutive passes of said mower 1 .
- said windrow grouping mechanism 6 is arranged behind said cutting mechanism 5 .
- said windrow grouping mechanism 6 comprises a bearing structure 16 supporting, on one hand, a longitudinal conveying device 17 and, on another hand, a transverse conveying device 18 .
- Said longitudinal conveying device 17 makes it possible to transport, in a direction opposite to said direction of forward travel 2 , the product cut by said cutting mechanism 5 .
- Said transverse conveying device 18 makes it possible, for its part, to move the cut product from said longitudinal conveying device 17 in a direction advantageously perpendicular to said direction of forward travel 2 .
- said windrow grouping mechanism 6 works as follows.
- said transverse conveying device 18 is connected to said bearing structure 16 by means of an articulation 21 the axis 21 a of which is substantially horizontal and perpendicular to said direction of forward travel 2 .
- Said transverse conveying device 18 can thus occupy at least one substantially horizontal position (FIGS. 1, 2, 3 ) and at least one retracted position (FIG. 4).
- said transverse conveying device 18 comprises an endless belt 19 wrapped around two cylinders 20 .
- Said cylinders 20 are advantageously directed in said direction of forward travel 2 . At least one of said cylinders 20 is driven in rotation about its longitudinal axis by means of a motor 34 .
- said longitudinal conveying device 17 comprises, according to an important feature of the present invention, at least one roller the longitudinal axis of which is substantially perpendicular to said direction of forward travel 2 of said mower 1 . Said roller is additionally driven with a rotational movement about said longitudinal axis so as to transport said cut product.
- said longitudinal conveying device 17 comprises three rollers 22 , 23 , 24 arranged, one behind the next, between said cutting mechanism 5 and said transverse conveying device 18 .

Abstract
Description
- 1. Field of the Invention
- The present invention relates to the overall technical field of agricultural machinery. It relates more specifically to a mower comprising:
- a frame,
- a cutting mechanism supported by said frame, and
- a mechanism for grouping windrows comprising a longitudinal conveying device and a transverse conveying device.
- 2. Discussion of the Background
- Such a mower is known in the state of the art. Indeed, VICON's “KMT/KMR 2400-3000-3200” brochure describes a trailed conditioning mower equipped with a belt-type grouper. In a way known to those skilled in the art, this mower comprises a cutting mechanism connected to a frame resting on the ground by means of two wheels. The belt-type grouper, arranged behind the cutting mechanism, is also supported by the frame. The cutting mechanism is intended to cut a standing product, for example grass. For its part, the grouper advantageously allows the product cut in at least two consecutive passes of the mower to be grouped together into a single windrow. What happens is that, during a first pass, the grouper of this known machine is pivoted upward into an inactive position. The product cut by the cutting mechanism is therefore deposited on the ground in the continuation of the mower. During a second pass, the grouper is lowered into an active position. In this case, the product cut by the cutting mechanism is transported, by means of the belt-type grouper, to be deposited to the side of the mower and onto the windrow from the first pass.
- In this known machine, the grouper is made up of a first belt running along a longitudinal axis of the mower and of a second belt arranged transversely to the mower. The first belt is intended to convey the forage from the cutting mechanism to deposit it onto the second belt. The latter in turn transports the forage to deposit it on the ground to the side of the mower. To this end, the first belt is produced by means of an endless belt wrapped around two cylinders. One of the cylinders, the axis of which is substantially horizontal, is arranged behind the cutting mechanism. The second cylinder, identical to the first cylinder, is, for its part, arranged above the second belt.
- This known embodiment of a longitudinal conveying device does, however, have a drawback. Specifically, in order to convey all of the cut product, the first belt is practically as wide as the cutting mechanism. In the case of mowers with wide cutting widths, it is then commonplace for the width of the first belt to exceed the distance between the two cylinders of which it is made. Such a configuration makes the endless belt difficult to guide over the cylinders. During work, this belt has a tendency to slip along the axis of said cylinders and therefore to rub against the structure of the grouper. This rubbing reduces the performance of the grouper and may even lead to tearing of the endless belt.
- The purpose of the present invention is to overcome this drawback of the state of the art.
- To this end, the mower according to the present invention is one wherein said longitudinal conveying device comprises at least one roller, the longitudinal axis of which is substantially perpendicular to a direction of forward travel of said mower, driven in rotation about said longitudinal axis so that its periphery transports the product, cut by the cutting mechanism, toward the rear of said mower. Thus, said mower does not have the drawback, described hereinabove, associated with the use of a very wide belt.
- Other features of the invention, to be considered separately or in any possible combination, will become further apparent from the following description of a nonlimiting exemplary embodiment of the invention depicted in the appended drawings in which:
- FIG. 1 depicts, in side view, a mower according to the present invention,
- FIG. 2 depicts, viewed on arrow II defined in FIG. 1, the mower of FIG. 1,
- FIG. 3 depicts, viewed in perspective on arrow III defined in FIG. 2, and on a different scale, an exemplary embodiment of the windrow grouping mechanism,
- FIG. 4 depicts, viewed in perspective on arrow IV defined in FIG. 2, and on a different scale, the windrow grouping mechanism of FIG. 3 in the inactive position.
- The
mower 1 depicted in FIGS. 1 and 2 is trailed in a direction and sense of forward travel indicated by thearrow 2. In the description that follows, the ideas of “front” and “rear”, “in front of” and “behind” are defined with respect to the direction offorward travel 2, and the ideas of “right” and “left” are defined when looking at saidmower 1 from the rear in the direction offorward travel 2. - In a way known to those skilled in the art, said
mower 1 comprises aframe 3 running along the ground by means of twowheels 4. Saidframe 3 supports, on one hand, acutting mechanism 5 and, on another hand, awindrow grouping mechanism 6. - In the exemplary embodiment depicted in FIGS. 1 and 2, said
frame 3 is connected to the rear of atractor vehicle 7 by means of adrawbar 8. Saiddrawbar 8 is connected to saidframe 3 by means of anarticulation 9 theaxis 9 a of which is directed upward. Saidarticulation 9 advantageously allows saidmower 1 to occupy, with respect to saidtractor vehicle 7, a transport position and at least one work position. - More specifically, in the light of FIG. 2, said
articulation 9 is situated at least substantially in a vertical mid-plane of saidmower 1. Thus, in a way known to those skilled in the art, saidmower 1 can be arranged in the continuation of saidtractor vehicle 7, as depicted in FIG. 2, to make it easier to transport by road. By pivoting saiddrawbar 8 with respect to saidframe 3 about saidarticulation 9, saidmower 1 can also be moved to the right or to the left of saidtractor vehicle 7. These two positions, used during work, advantageously allow saidmower 1 to work back and forth. In the exemplary embodiment depicted in FIGS. 1 and 2, the pivoting of saiddrawbar 8, and therefore the placement in the work position or the placement in the transport position, is brought about by means of aram 10 connected, on one hand, to saidframe 3 and, on another hand, to saiddrawbar 8. - In FIG. 1, said
frame 3 has been partially depicted in section so as to make saidwindrow grouping mechanism 6 visible. In FIGS. 1 and 2, it will also be noted that not all of the length of saiddrawbar 8 has been depicted. - In a way known to those skilled in the art, said
cutting mechanism 5 is connected to saidframe 3 by means of a suspension device. During work, as depicted in FIG. 1, saidcutting mechanism 5 rests at least partially on theground 12. Said suspension device advantageously allows at least some of the weight of saidcutting mechanism 5 to be transferred to saidframe 3. In addition, said suspension device allows saidcutting mechanism 5 to follow the unevenness of saidground 12 independently of saidframe 3. Such a suspension device is known to those skilled in the art and will therefore not be described further and, for reasons of clarity, has not been depicted in the figures. - Said
cutting mechanism 5 comprises cuttingmembers 11 intended to cut a standing product, these members being arranged in a line at least substantially perpendicular to said direction offorward travel 2. Eachcutting member 11, depicted symbolically in FIG. 2, is driven in rotation about an upwardly-directedrespective axis 11 a. - In the exemplary embodiment depicted in FIGS. 1 and 2, said
cutting mechanism 5 also comprises atreatment device 13 intended to accelerate the drying of said cut product. In a way known to those skilled in the art, saidtreatment device 13 is produced by means of aconditioning rotor 14 arranged behind said cuttingmembers 11. Saidrotor 14 is driven in rotation about anaxis 14 a which is substantially horizontal and perpendicular to said direction offorward travel 2. - The cutting
members 11 and thetreatment device 13 of saidcutting mechanism 5 are driven in rotation, off a power take-off of saidtractor vehicle 7, by means oftransmission members 15. Saidtransmission members 15 are known to those skilled in the art and will therefore not be described further. - For its part, said
windrow grouping mechanism 6 is intended to group together, into a single windrow, the product cut during at least two consecutive passes of saidmower 1. For that purpose, saidwindrow grouping mechanism 6 is arranged behind saidcutting mechanism 5. In addition, saidwindrow grouping mechanism 6 comprises a bearingstructure 16 supporting, on one hand, a longitudinal conveyingdevice 17 and, on another hand, a transverse conveyingdevice 18. Said longitudinal conveyingdevice 17 makes it possible to transport, in a direction opposite to said direction offorward travel 2, the product cut by saidcutting mechanism 5. Said transverse conveyingdevice 18 makes it possible, for its part, to move the cut product from said longitudinal conveyingdevice 17 in a direction advantageously perpendicular to said direction offorward travel 2. - In the exemplary embodiment depicted in the figures, said
windrow grouping mechanism 6 works as follows. - During a first pass of said
mower 1, said transverse conveyingdevice 18 is rendered inactive. The product, cut by thecutting mechanism 5 and transported to the rear by means of said longitudinal conveyingdevice 17, is thus deposited in the continuation of saidmower 1. - During a second pass of said
mower 1, said transverse conveyingdevice 18 is activated. As a result, the product, cut by thecutting mechanism 5 then transported to the rear by means of said longitudinal conveyingdevice 17 and finally moved sideways by said transverse conveyingdevice 18, is thus deposited to the side of saidmower 1 and onto the windrow from said first pass. - To do this, in the exemplary embodiment depicted in the figures, said transverse conveying
device 18 is connected to saidbearing structure 16 by means of anarticulation 21 theaxis 21 a of which is substantially horizontal and perpendicular to said direction offorward travel 2. Said transverse conveyingdevice 18 can thus occupy at least one substantially horizontal position (FIGS. 1, 2, 3) and at least one retracted position (FIG. 4). In addition, said transverse conveyingdevice 18 comprises anendless belt 19 wrapped around twocylinders 20. Saidcylinders 20 are advantageously directed in said direction offorward travel 2. At least one of saidcylinders 20 is driven in rotation about its longitudinal axis by means of amotor 34. - In the substantially horizontal position (FIGS. 1, 2,3), the cut product from said longitudinal conveying
device 17 drops onto the top of saidendless belt 19. In consequence, said transverse conveyingdevice 18 is active. By contrast, in the retracted position (FIG. 4), said transverse conveyingdevice 18 is pivoted upward about saidarticulation 21. The cut product from said longitudinal conveyingdevice 17 passes under saidendless belt 19 and drops directly onto the ground. Said transverse conveyingdevice 18 is therefore inactive. - The pivoting of said transverse conveying
device 18 about saidarticulation 21 is advantageously brought about by means of aram 22. As this embodiment of a transverse conveyingdevice 18 is known to those skilled in the art, it will not be described further in detail. It will be noted that saidendless belt 19 has not been depicted in FIG. 3, in order to make saidcylinders 20 visible. - For its part, said longitudinal conveying
device 17 comprises, according to an important feature of the present invention, at least one roller the longitudinal axis of which is substantially perpendicular to said direction offorward travel 2 of saidmower 1. Said roller is additionally driven with a rotational movement about said longitudinal axis so as to transport said cut product. - In the exemplary embodiment depicted in the figures, said longitudinal conveying
device 17 comprises threerollers mechanism 5 and said transverse conveyingdevice 18. Eachroller longitudinal axis forward travel 2. - As a preference, said
longitudinal axes device 18 lies a relatively significant distance off the ground so that the cut product can be thrown out a long way to the side during the second pass of saidmower 1. Said longitudinal conveyingdevice 17 therefore also has the role of lifting the forage up from saidcutting mechanism 5 as far as said transverse conveyingdevice 18. - In order to transport the cut product, each
roller longitudinal axis rollers 24 is driven in rotation by means of ahydraulic motor 28. This rotational movement is then transmitted to theother rollers - In the exemplary embodiment depicted in the figures and more specifically in FIG. 3, each
roller rollers mower 1. Said half-rollers longitudinal axis rollers 221; 231 situated in front and to the right of said longitudinal conveyingdevice 17 have not been depicted in FIG. 3. - Said half-
rollers bearing structure 16 by means of acasing 29 arranged at least substantially in said vertical midplane. Said casing 29 on one hand guides the half-rollers casing 29 contains said transmission elements (not depicted), produced, for example, in the form of a train of gears, a belt or a chain. Advantageously, saidcasing 29 is connected to saidbearing structure 16 by means of twoarticulations 30 equipped with dampers, for example rubber buffers. - In the light of FIG. 3, said
hydraulic motor 28 is also connected to saidbearing structure 16 by means of asupport 31. The connection between saidsupport 31 and saidbearing structure 16 is also made by means of anarticulation 32 equipped with dampers. Saidsupport 31 also plays a part in providing said longitudinal conveyingdevice 17 with good stability. - In a particularly advantageous way, said
bearing structure 16 is connected removably to saidframe 3. Saidwindrow grouping mechanism 6 can thus constitute a kit that can easily be added to or removed from amower 1. Said kit may also contain a hydraulic pump (not depicted), intended to be connected to saidmower 1 and driven by saidtransmission members 15. Said hydraulic pump will allow saidhydraulic motor 28 of said longitudinal conveyingdevice 17 and saidmotor 34 intended to move saidendless belt 19 of said transverse conveyingdevice 18 to be driven. - The mower which has just been described is merely one exemplary embodiment which must not in any way be taken to limit the field of protection defined by the claims which follow.
- Specifically, the present invention relates also to
mowers 1 comprising noconditioning device 13 or comprising a different conditioning device 13 (consisting, for example, of two contrarotating rollers). - Likewise, said longitudinal conveying
device 17 may comprise a different number ofrollers - In another exemplary embodiment, not depicted, each
roller rollers rollers hydraulic motor 28 directly drives a transmission element present in saidcasing 29.
